Hey guys, drove around today with no problems, but on my way back home, sounded initially like i had a flat tire, then realized was the engine.

Car sounds like a wrx (which isn't normal lol), if i'm rolling along, the engine will stutter, especially when accelerating. When travelling along, the engine will slow down then burst forward for a sec, then back down etc.

Got a booking fr Trojan on Thursday, but its a 40-50 min drive from my place, and seemed to be getting worse on the 10 min drive to my place.

Any idea what it could be? Just wondering if I should drive it on Thursday, or get it looked at by someplace close perhaps tomorrow or tuesday first.

The only weird thing I can think that happened, was yesterday, my nan was watering the garden and somehow lost the hose, went under the car and drenched the engine bay from underneath. I noticed the pod filter was a bit wet but left it overnight/day to dry and like i said, it ran fine......

If you haven't guessed, i know next to nothing about this stuff...

If your pod filter's wet then it's very likely that you've gotten your airflow meter wet. Could be that. It could also be the electrical contact for the crank angle sensor has gotten wet, which isn't far from the air filter.

Could be your coilpacks starting to bomb out by coincidence, but that only really happens when you rev/boost it hard and flat footed (initially).

Does it matter if the engine's warm or not?

Thanks mate,

Nah dosn't matter if the engine is warm, drove home which was like 15-20 min drive, did it the whole way

Should mention that my engine is stock. just got the pod and zorst.

my silvia (RB20) sounded like a wrx when running on 5 cylinders on idle but as soon as you started driving itd run on 6 cyls. possibly coils. just get some splitfires and see what happens.

could it be the spark plugs not firing right

I'm not sure, that was my initial thoughts. Hmmmm...... Might drive it to my local place, see whats wrong, if they gotta replace stuff i would prefer trojan to do it - except not really wanting to drive it all the way there lol.

.......or depending if you can get it to do it at idle

easy way to test the coils is by unplugging them one at a time. whichever one doesn't make a difference.... will have some issue with it.

man i had the exactly same issues here. my RB25de Neo have some trouble with missfiring. because it sounds like a WRX. probably chilling winter in canberra?

if u start the car in the morning (or when the engine is cold) it sounds ok for 5 minutes (because the car automatically retard the firing). after 5 mins the timing gets advanced to normal state, thats when the engine sounds like WRX.

i'm opening my intake plenum now and will open the cover tomorrow to check and replace the spark plugs / coils / looms. or even injectors.

if u'll bring it to local workshop, will u share the answers with me?

cheers.

One thing he's forgotten to tell you though don't unplug them/plug them in while the car's running... right James? :D

OMG TOOK THE SPARK PLUGS OUT WHILE IT WAS RUNNING AND THE ENGINE WON"T START NOW>.......

just kidding ;-)

Thanks guys, getting it towed to trojan tomorrow. gtrkat, your price was spot on! Thanks!

Trojan thinks it could be the spark plugs or coil packs ;-)

Will see on wed/thurs. Hopefully won't break my bank account...fingers crossed!

Good luck mate, i had an issue with mine not long ago where it would just stop accelerating all together, then it'd kick back in and cut back out, all within the space of a few seconds. Took it to Ed at AutoTech and it turned out to be the solder on the wires in the AFM had come loose and were barely making contact causing the PowerFC to think there was no airflow coming in and cutting the power. To make matters worse had a grounding issue at the same time and one problem masked the other.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
